Overview
- Tesla began an early-access rollout of Full Self-Driving v14 'Lite' for Hardware 3 vehicles, a phased release that started June 29, 2026 and will expand to more owners over the next few weeks based on feedback.
- The 'distillation' process compresses driving behavior from the newer HW4 v14 stack so HW3 computers can run reinforcement-learning and offline models, and it adds parking, unparking, reversing, Arrival Options, and always-on Speed Profiles.
- v14 'Lite' remains a supervised Level 2 driver-assist system that requires hands-on supervision and does not enable unsupervised autonomy on HW3.
- Tesla says the technical barrier is HW3’s much lower memory bandwidth—about 15% to one-eighth of HW4—which prevents running full unsupervised FSD without replacing the computer or cameras.
- Owner pressure and legal claims continue as affected buyers seek compensation or hardware fixes; Tesla has proposed discounted trade-ins or a paid retrofit that likely won’t scale widely until mid-2027, and regulatory checks will govern international rollouts.
